Evaluation de lâactivite antifalcimiante de differents extraits des graines de Cajanus cajan (Fabacees) sur les drepanocytes a Abidjan-Cote dâIvoire
Les coĂ»ts onĂ©reux du traitement dans la drĂ©panocytose conduisent, les patients Ă sâorienter vers la mĂ©decine traditionnelle. Une Ă©tude antĂ©rieure a montrĂ© lâactivitĂ© antifalcimiante de lâextrait aqueux des graines de Cajanus cajan (FabacĂ©es). En vue dâidentifier lâextrait le plus actif, il a Ă©tĂ© proposĂ© comme objectif dâĂ©valuer in vitro lâeffet antifalcimiant de diffĂ©rents extraits des graines de Cajanus cajan. LâĂ©tude de lâactivitĂ© antifalcimiante sâest faite sur les prĂ©lĂšvements sanguins de 32 drĂ©panocytaires homozygotes SSFA2. AprĂšs induction de la falciformation des globules rouges, lâajout dâun extrait dans chaque tube a permis dâĂ©valuer lâactivitĂ© antifalcimiante par le dĂ©compte des drĂ©panocytes au microscope optique. Les extraits des graines de Cajanus cajan contiennent des stĂ©rols, polyterpĂšnes, polyphĂ©nols, des flavonoĂŻdes et des alcaloĂŻdes. Tous les extraits diminuaient le taux de drĂ©panocytes dâenviron 60% aprĂšs 30 mn de contact. Cette Ă©tude a permis de montrer que les diffĂ©rents extraits des graines de Cajanus cajan possĂšdent des vertus antifalcimiantes tout comme lâextrait aqueux.Mots clĂ©s: Cajanus cajan, extraits, activitĂ© antifalcimiante, AbidjanEnglish Title: Evaluation of the antisickling activity of different extracts of Cajanus cajan (Fabacees) seeds on sickle cells in Abidjan-Cote dâIvoireEnglish AbstractThe expensive costs of treatment in sickle cell disease lead patients to move towards traditional medicine. A previous study showed the antifalcimiant activity of the aqueous extract of the seeds of Cajanus cajan (Fabaceae). In order to identify the most active extract, it has been proposed to evaluate in vitro the antifalcimiant effect of different extracts of Cajanus cajan seeds. The study of antifalcimiante activity was done on the blood samples of 32 SSFA2 homozygous sickle cell patients. After induction of sickling of the red blood cells, the addition of an extract in each tube made it possible to evaluate the antifalcimiant activity by the counting of the sickle cells under an optical microscope. The extracts of Cajanus cajan seeds contain sterols, polyterpenes, polyphenols, flavonoids and alkaloids. All extracts decreased the sickle cell count by about 60% after 30 minutes of contact. This study has shown that the different extracts of the seeds of Cajanus cajan possess antifalcimiante virtues just like the aqueous extract.Keywords: Cajanus cajan, extracts, antifalcimiant activity, Abidja
